    Overview
As of August 2022, a 1TB SSD is getting tight to run an Ethereum node in. The recommendation now is for 2TB of space. I wanted to see what it takes to still fit into 1TB.
EIP-4844 will increase space need by another 34 GiB or so. This is a 2023 discussion however.
Options

Geth 1.11 without prune ... experimental for now.


Any use of Geth on a staking node comes with risk for the node operator, as long as Geth still has a supermajority (greater 2/3rd) of the network.


Nethermind with online prune ... this takes some careful setup, and can work. Run Nethermind with hybrid prune, when disk space is at 250 GiB free, start a full prune, when prune is done, restart it, and GOTO 1.


Future Nethermind without prune ... timeline unknown


Future Besu with storage optimizations ... even with Bonsai tries it grows at ~ 8 GiB/week, and it cannot be pruned


Erigon without prune, on ZFS w/ lz4 and 16k recordsize ... possibly if setting ZFS parameters just so and --db.pagesize=16k for Erigon. Testing.


Keep an eye on EIP-4444, which will drastically reduce the need for state storage.
